Unilateral ECT as a Test for Cerebral Dominance, with a Strategy for Treating Left-handers

Abstract
The growing adoption of ECT given unilaterally to the right hemisphere in right-handed patients, in preference to the classical bilateral treatment, is due to its shortening of the duration of post-treatment confusion, to its superiority in preserving memory and learning assessed three months after the start of treatment (Halliday et al., 1968) and to its therapeutic equivalence. (For a critical assessment of published results, see d'Elia, 1970.)
